Section 10.12 Cloning Lists
If we want to modify a list and also keep a copy of the original, we need to be able to make a copy of the list itself, not just the reference. This process is sometimes called cloning, to avoid the ambiguity of the word copy.
The easiest way to clone a list is to use the slice operator.
Taking any slice of
a
creates a new list. In this case the slice happens to consist of the whole list.Now we are free to make changes to
b
without worrying about a
. Again, we can clearly see in codelens that a
and b
are entirely different list objects.You have attempted of activities on this page.
